All Implemented Interfaces:

ParseExceptionListener, SIPMessageListener, RawMessageChannel, Runnable

public class TLSMessageChannel
extends ConnectionOrientedMessageChannel

This is sipStack for TLS connections. This abstracts a stream of parsed messages. The SIP sipStack starts this from the main SIPStack class for each connection that it accepts. It starts a message parser in its own thread and talks to the message parser via a pipe. The message parser calls back via the parseError or processMessage functions that are defined as part of the SIPMessageListener interface.

Constructor Detail

TLSMessageChannel

protected TLSMessageChannel(Socket sock,
                 SIPTransactionStack sipStack,
                 TLSMessageProcessor msgProcessor,
                 String threadName)
                     throws IOException

Constructor - gets called from the SIPStack class with a socket on accepting a new client. All the processing of the message is done here with the sipStack being freed up to handle new connections. The sock input is the socket that is returned from the accept. Global data that is shared by all threads is accessible in the Server structure.

Parameters:

sock - Socket from which to read and write messages. The socket is already connected (was created as a result of an accept).

sipStack - Ptr to SIP Stack

msgProcessor - -- the message processor that created us.

Throws:

IOException

TLSMessageChannel

protected TLSMessageChannel(InetAddress inetAddr,
                 int port,
                 SIPTransactionStack sipStack,
                 TLSMessageProcessor messageProcessor)
                     throws IOException

Constructor - connects to the given inet address.

Parameters:

inetAddr - inet address to connect to.

sipStack - is the sip sipStack from which we are created.

messageProcessor - -- the message processor that created us.

Throws:

IOException - if we cannot connect.

Method Detail

close

public void close(boolean removeSocket,
         boolean stopKeepAliveTask)

Close the message channel.

Specified by:

close in class ConnectionOrientedMessageChannel

getTransport

public String getTransport()

get the transport string.

Specified by:

getTransport in class MessageChannel

Returns:

"tcp" in this case.

sendMessage

protected void sendMessage(byte[] msg,
               boolean retry)
                    throws IOException

Send message to whoever is connected to us. Uses the topmost via address to send to.

Specified by:

sendMessage in class ConnectionOrientedMessageChannel

Parameters:

msg - is the message to send.

retry -

Throws:

IOException

sendMessage

public void sendMessage(byte[] message,
               InetAddress receiverAddress,
               int receiverPort,
               boolean retry)
                 throws IOException

Send a message to a specified address.

Specified by:

sendMessage in class MessageChannel

Parameters:

message - Pre-formatted message to send.

receiverAddress - Address to send it to.

receiverPort - Receiver port.

Throws:

IOException - If there is a problem connecting or sending.

handleException

public void handleException(ParseException ex,
                   SIPMessage sipMessage,
                   Class hdrClass,
                   String header,
                   String message)
                     throws ParseException

Exception processor for exceptions detected from the parser. (This is invoked by the parser when an error is detected).

Parameters:

sipMessage - -- the message that incurred the error.

ex - -- parse exception detected by the parser.

header - -- header that caused the error.

message - -- message where this header was detected.

Throws:
